Telefonica Germany will move one million 5G customers to Amazon Web Services (AWS) cloud later this month, company executives told Reuters, in a bold move by the U.S. online retailer to break into the global telecoms market. While some telecom networks have moved IT and other non-core operations to the public cloud, the move by the subsidiary of Spanish group Telefonica is a global first where an existing mobile operator is switching its core network to a public cloud.
